IMPROVEMENT IN WIRE ROPES AND CABLES.

Specification forming part of Letters Patent No. 202,812, dated April23, 187B application filed January 9, 1878.

To all whom it may concern:

Be it known that I, THEoDoR HAGER, of the city of Mayence, in the GermanEmpire, have invented an Improved Wire Hope or (Jable, of which thefollowing is a specification:

My invention relates to the construction of wire ropes and cables, andtheir peculiar adaptation to mechanical purposes; and consists, first,in arranging the wires in bundles or fascines, all the wires beingparallel to each other, instead of twisting the wires or strands ofwires together, as has been the practice heretofore, whereby greaterpliability and tensile strength are obtained, and in inclosing thebundlesin a series of loosely-fittingmetallic sleeves, to allow freeplay of the wires within said sleeves, and to permit of the bundle orrope so formed being readily and easily bent; secondly, in providingsuitable means for uniting the ends of the wires together, and forforming an endless rope, or for attaching said rope to or 0011- nectingit with any other mechanical device.

Figure 1 illustrates a round rope or cable constructed according to myinvention, one of the binding-sockets being in section. Fig. 2 is asection through line '0 o of Fig. 1. Figs. 3 and 4 are edge and planviews, respectively, partly in section, of a fiat rope or wire bandconstructed according to my invention.

In the accompanyingdrawings, a a represent a series of wires, or a wirefascine or bundle, in which all the wires are laid parallel with eachother, either to form a round rope, asin Figs. 1 and 2, or a band orflat rope, as in Figs. 3 and 4. The fascine or bundle is containedwithin a series of loosely-fitting sleeves or rings, b b, in which thewires to a have free play. These sleeves are slipped over the bundleafter one end thereof has been bound together, in the manner and by themeans hereinafter described. The sleeves or rings b are not pushed orjammed too close together, as the rope in such case would have little orno pliancy, suflicient room being given between the sleeves or rings bto admit of the ready bending of the rope. By these means themanufacture of wire ropes is not only simplified considerably, but theropes are more pliant and possess greater tensile strength than thoseconstructed in the usual Way, as Will be readily understood.

0 is a metallic cylindrical or flattened socket, (tapering from top tobase, and provided with perforated ears c,) serving to unite and firmlyhold the ends of the wires a forming the bundle, and providing meanseither for forming an endless rope, by pivoting the two end sockets c ofa rope together, or for attaching said rope to or connecting it with anyother mechanical device. The manner in which the ends of the bundle aremade fast within the socket may be varied. Forinstance, the wires a,after being slipped through the smaller end of the tapering socketsufficiently to permit of their being bent, are drawn back again intothe socket after having been bent or doubled, and may then be firmlyunited with each other and with the socket c by filling the latter withsolder or other metal while in a state of fusion, as shown by Fig. 1; orthe wires of the bundle may be slipped through the socket c by the smallend, and then bent around a wedge, (I, as shown by 3 and 4.

It will be evident that the greater the strain upon the rope the tighterit is wedged within the socket c; butto further secure against theaccidental straightening of the ends of the wires by the strain exertedupon the rope, bend the wires around the Wedge in such manner that theends, when drawn down into place within the socket, will project belowthe lat ter sufficiently to permit of an additional sleeve or ring, b,being slipped over said ends, which are then bent over the sleeve 1),and may be wired or tied into position, if desired, as fully shown atb", Fig. 3.

Instead of the perforated ears 0, I may use a screw'plug, 0 providedwith an eye,c ,which plug is tightly screwed into the enlarged end ofthe socket 0, its inner periphery being correspondingly threaded, aswill be readily understood.

I am aware that the construction of wire cables with their componentwires laid parallel to each other is not new, and I do not claim thisconstruction,broadly, nor the means heretofore employed to bind thebundles by means of wires from distance to distance, as

the method employed by me is much superior to that heretofore employed.WVhen the bundle of wire is inclosed in a series of looselyfittingsleeves, within which the component wires have free play, I obtain astronger and more pliable cable or rope, and have the further advantageof giving this rope any desired form in cross-section, either round,flat, or angular, according to the shape of the sleeves employed tocontain the wires, while by the method heretofore employed round cablesor ropes can be made only, and, owing to the tight binding, these ropesor cables have but a limited pliability.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is
